欢迎回到2011年《Spring一周动态》的最后一期。难以置信，我们已经做了一年了！时间都去哪儿了？俗话说，忙碌充实的时间总是过得飞快……

一直以来，我们的目标是希望这些回顾能让开发者更容易地了解Spring社区的动态。SpringSource和VMware的公告、发布、内容，以及社区创作的海量内容，总有精彩纷呈的事情在发生。

虽然本周有很多精彩的内容，但我们将在下周再进行常规回顾。本周，我们将回顾2011年Spring社区的这一年。

	<lI>  <B>Spring 3.1</B> Development of Spring 3.1 began in earnest in early 2010, and by SpringOne 2GX 2010 we already had an idea of what it was going to look like. By the beginning of this year, <a href ="http://www.springsource.org/node/3026">we already had milestones</a> to play with.  
  As the year progressed, we saw numerous new milestones, followed in short order by release candidates. The release candidates progressed and then, finally, a couple of weeks ago, we <a href = "http://www.springsource.org/node/3335">got Spring 3.1 GA</a>. 

在 Spring 3.1 的众多令人兴奋的新功能和主题中，有一个

• 大大改进的 Java 配置模型
• 针对 JPA 和 Spring MVC 应用程序的增强型、纯 Java 配置。
• Profiles，它允许您为配置中的 Bean 定义两次，然后在应用程序运行时所处的环境基础上激活给定的定义。
• 一个 Environment 抽象
• 一个 声明式的、面向注解的缓存模型
• 一个改进的 单元测试体验
• Hibernate 4 支持

		<B>The Cloud and Cloud Foundry</B> 
		
		 In April of this year, <a href ="http://blog.springsource.org/2011/04/12/launching-cloud-foundry/">SpringSource and VMWare launched   Cloud Foundry</A>, the open source Platform as a Service. <a href = "http://cloudfoundry.org">Cloud Foundry</a> can be run on-premise. 
		
		Cloud Foundry is an open-source Platform-as-a-Service (PaaS). Cloud Foundry works with many languages, runtimes, and services. And, if the list of supported services and runtimes wasn't enough, one only had to wait to see <a href="http://blog.cloudfoundry.com/post/6109591023/cloud-foundry-now-supporting-scala"> Scala</a> support, <a href ="http://blog.springsource.org/2011/08/30/using-postgres-on-cloud-foundry/">PostgreSQL</a> support, <a href = "http://blog.springsource.org/2010/04/13/springsource-acquires-rabbitmq/">RabbitMQ</a> support and <A href = "http://blog.cloudfoundry.com/post/13481010480/cloud-foundry-welcomes-net-framework-community-contributions">.NET</a> support added in the months that followed.
		
	 
			Cloud Foundry works <a href = "http://blog.springsource.org/2011/10/13/using-cloud-foundry-services-with-spring-part-1-the-basics/">brilliantly</a> with <a href ="http://blog.springsource.org/2011/11/04/using-cloud-foundry-services-with-spring-part-2-auto-reconfiguration/">Spring applications</a>.
			
			 You can use the <a href = "http://blog.springsource.org/2011/11/09/using-cloud-foundry-services-with-spring-applications-part-3-the-cloud-namespace/"> &lt;<CODE>cloud</CODE>&gt;</a> namespace or Java configuration in tandem with the Cloud Foundry library to interrogate and work with the services provisioned by Cloud Foundry. <a href ="http://blog.springsource.org/2011/11/10/using-cloud-foundry-services-with-spring-part-4-%e2%80%93-spring-profiles/">Spring 3.1 profiles can be used to to good effect on Cloud Foundry</a> to conditionally reference data sources that are managed  by the cloud when your application's run in the cloud. Spring AMQP and Spring Integration make  it simple <a href = "http://blog.springsource.org/2011/08/16/chatting-in-the-cloud-part-1/">to build messaging applications using RabbitMQ</a> on Cloud Foundry, and the Spring Data projects make it dead simple to build applications that work with <a href = "http://blog.springsource.org/2011/05/03/using-mongodb-redis-node-js-and-spring-mvc-in-a-single-cloud-foundry-application/"> MongoDB, and  Redis</a> on Cloud Foundry. There is of course <a href = "http://blog.springsource.org/2011/08/24/using-micro-cloud-foundry-from-grails/">Grails support</a> and <a href ="http://blog.springsource.org/2011/04/12/roo-cloud-foundry-productivity-in-the-cloud/">Spring Roo support</a>. <a href = "http://blog.springsource.org/2011/08/24/micro-cloud-foundry-for-spring-developers/"> Cloud Foundry released Micro Cloud Foundry</a>, a virtual machine with a fully configured cloud that you could use to develop your Spring applications locally. To support automated builds with Cloud Foundry, <a href="http://blog.springsource.org/2011/09/22/rapid-cloud-foundry-deployments-with-maven/">developers can use the Maven plugin</a>.

	<LI> <B>Big Data</B> 
		2011 delivered the implementation of the NoSQL data integration vision that Rod Johnson described way back at SpringOne 2GX 2010. 
		
   This year saw  many Spring Data projects reach or exceed 1.0 releases (and the numerous milestones and release candidates that precede GA releases!), including  <a href = "http://blog.springsource.org/2011/02/10/getting-started-with-spring-data-jpa/">Spring Data JPA</a> and  <a href = "http://www.springsource.org/node/3302">Spring Data Neo4J</a>, <a href  = "http://www.springsource.org/node/3346">Spring Data MongoDB</a>, <a href ="http://www.springsource.org/node/3337">Spring Data Redis</a>, <a href = "http://www.springsource.org/node/3336">Spring Data GemFire</a>, and the evolution of numerous other interesting projects like <a href = "https://github.com/SpringSource/spring-hadoop">Spring Hadoop</a>, and the concept of <a href = "http://blog.springsource.org/2011/07/27/fine-tuning-spring-data-repositories/">Spring Data Repositories</a>.

	<LI>  <B>Mobile and The Next Generation Web </B>  
		
		 The web's a big place, and it comes in many form factors.  
	
	Today, delivering an application means delivering it  through the web, and on  mobile platforms like Android and iOS. 
		
		A huge  part of building better mobile applications is building  RESTful services for  communication between client and a server in a standard, interoperable way.
		
		

Spring Core 提供了 `RestTemplate`，它促进了客户端和服务器之间的 RESTful 通信。

Spring Android 支持从 Android 设备消费 RESTful Web 服务。

This year even saw the creation of some great information for <a href = "http://blog.springsource.org/2011/08/26/clean-code-with-android/"> building cleaner Android applications overall</a>. 		
 

As powerful as REST is, it can't be the full story. A critical piece of the pie is security, and authorization. After all,  Facebook can't very well go around exposing your data through a RESTful service that you haven't explicitly authorized it to. The last few years bore witness to the rise of the various OAuth standards, and implementations by the various 	service providers like Facebook, Twitter, etc. <a href = "http://blog.springsource.com/2011/09/08/spring-social-1-0-what-a-year-makes/">Spring Social went GA this year</a> and it supports communication with these services through OAuth. Spring Android also supports Spring Social, making it ideally trivial to consume OAuth-secured, RESTful services from

Android 应用程序。此外，Spring Security OAuth，一个专注于帮助人们使用 OAuth 公开安全服务的 Spring Security 项目，也于今年开始迈向 GA（General Availability）。
